"The Dungeons of Castle Blackmoor": ZGG, 2006.

[Persimmon]

Well, DriveThru RPG dropped the price of the Dungeons of Castle Blackmoor pdf to a mere $4.50 so I decided to snap it up. A cursory look indicates that converting it to B/X won't be too difficult. And as it turns out, I recently picked up the Adventurer Conqueror King System because I was interested in adding their new classes to our OSE game and I've been toying with the idea of a campaign that culminated in domain play featuring some kind of major war. Blackmoor would seem to be an ideal setting for such a campaign.

So that will be my next big project after the current megadungeon I'm writing up for our Castles & Crusades campaign.
